Just about to finish up 7M GTE rebuild with some mods. After market intercooler and pipes, the "3000" replacement pipe does not have bung for hose that goes to the vacuum switched 1/2" hose that I don't know the function of. Does someone have a diagram of all the vacuum lines and what is...

Wish I had heard of this sooner. Engine is back in the car and only lacks running oil lines and mounting thermostat and filter housing. The braided line looked great, and wonder in what way it is prone to fail? Seems like the same type of line run on many race cars. Please advise further if...

I have had bearing failure and believe it was caused by low oil pressure when coming off the interstate after running 80mph on hot day and then pulling up to stop light. The pressure went down and of course the stock cooling came out of the circuit. I always begin by using a known good...

I have been unable to find a replacement crank for cheap. Ebay shows one unmolested and stock size for $500, and crank kits with bearing are about $450. Ohio Crankshafts is re-nitriting my crank for $125 (plus shipping and me constructing a box from 2x8 wood). I'll eat the cost of turning...

Bump, does no one have an opinion on re-treating the crank? I did ask Aaron at Driftmotion and he said he would advise scrapping this crank and get another one. If most of you feel this is the only way to go I guess I can eat the $200 I will have in this crank when it comes back from being...

I am seeking all the input I can get on this issue (no offense to IJ) and one shop which does retreat/harden cranks for race engines says my crank should be fine in a "stock" engine, as cutting nitrited cranks 30 thou is done all the time. Problem is, engine is already modded some, and if we...

Rats! Anyone have best deals on crank kit?

Any one else want to confirm this crank can not take more than 15 thou cut on rod throws? This comes as quite a surprise to me. I have not known of any crank since studebaker that had such a thin hard surface. I really need to know if this is true before I pour more $ into this engine.

Machine shop has turned crank rods .030, mains .010, straightened crank run out, resized two rods (# 3 + 4) and cleaned up block and crank(with plugs removed this time) rods and pistons and say all is good. Reassembly will include driftmotion blue printed oil pump, braided cross over pipe...

Does anyone sell a complete kit for 7M GTE to relocate filter and add cooler, thermostat? For street use is it necessary to use expensive fittings and hose, or will push lock with clamps do the job? What size minimum hose and fittings are recommended? Thanks!

I was unaware that one must always replace a rod that has had a spun bearing. I always have my machine shop resize and check all rods, but I'm not sure they always tell me to replace them. Sure if a rod has no bearing material left when you take it apart it is likely beyond repair, but if each...

Thanks for all the replies. Nathaninwa it would be great if you could send me a sample oil report with Blackstone's contact info. I really think the clearances were OK, but agree with oil starvation being the likely cause. Also wonder if possible fuel injector leak may have contaminated the...

Just removed all crank plugs and found some gunk under each plug (worst at rear two plugs) not blocking the passages, but a total amount of stuff the size of a small marble perhaps. Material was like soft clay and built up against back side of plugs. Not nice, but I don't think this is the...

I don't think the crank plugs were ever pulled so I will do this myself and see how much crud is there. Engine does have unusual residue in the oil pan which I was thinking was left over assembly lube, but after one oil change at 400 miles and another at 1500, perhaps this is a sign of...

Mostly stock, pistons +.020, turbo elbow and exhaust all modified, stock boost so far, best gas I can buy, castrol 10w-30. Just finished tear down and all bearings are bad. One rod bearing on #4 showing copper, all others show signs of even but excessive wear, mains look bad as well. All...

This block was was cleaned by machine shop prior to last build (2k miles ago) however, since I will have it down, I'll do it again. Got to say, it looks very clean but why take chances. Should of had a V-8!

Those of you who have read my earlier posts already know the long sad story, but a brief re-hash in case you don't. Bought a "good" JDM turbo 7MGTE to replace tired NA engine. After finding the correct wiring harness, ECU ect. ran it 2000 miles, changed to full synthetic and spun #6 rod...

There has been much written about oil pressure vs: oil flow in earlier threads and some have rather strong opinions about this issue. Stock spec's for oil pressure are lower than yours, and the most members seem to believe that your numbers are entirely adequate. For other performance engines I...

55 years doing brake jobs and taking training courses I've never been told much of what is said here. Your information is so detailed and well written I will try these techniques. Thanks!

That makes sense and I will do the plasti-gauge check, but still, the only way I can see this happening so quickly would be if a cam cap worked loose and mine were all tight. Anyhow, easy enough to check all these issues.
